  In the above-described known technology, since the frame is made of a metal material, the weight is heavy and the performance such as flexibility is poor, which is a bottleneck in improving the performance of the fishing rod. For example, in a fishing rod that is required to be lighter, if a large number of fishing line guides as described above are attached along the axial length direction, desired performance cannot be exhibited. Further, when a large load is applied, such as when a fishing line is caught, deformation is likely to occur.

  The present invention has been made by paying attention to the above-described problems, and it is an object of the present invention to provide a fishing line guide that can be reduced in weight and has excellent deflection characteristics and a method for manufacturing the same.

In order to achieve the above-described object, a method for manufacturing a fishing line guide according to the present invention includes a plurality of reinforcing fibers along a direction in which a groove is formed in a frame forming groove formed in a mold. A fiber bundle is accommodated, and a synthetic resin is filled in the groove of the mold to form a frame made of fiber reinforced resin .

As described above, the frame of the fishing line guide according to the present invention has a frame forming groove formed in the mold, and the reinforcing fiber is accommodated in the groove portion along the groove direction. It is formed by filling the groove with a synthetic resin.

In order to achieve the above-described object, the fishing line guide according to the present invention includes a frame, a holding part for holding a guide ring through which the fishing line is inserted, a fixing part for attaching a fishing rod, and the holding part and the fixing part. And the fiber bundle is folded so as to circulate around the holding portion from one end side of the fixing portion and the connecting portion, and the other of the connecting portion and the fixing portion. It is characterized by being continuously arranged so as to reach the end side.

Since the fishing line guide having the above-described structure is made of fiber reinforced resin, the weight of the fishing line guide can be reduced, and the fishing rod equipped with the fishing line guide having such a structure can easily exhibit its original characteristics. Further, since the fiber reinforced resin constituting the frame is disposed in a state in which the direction of the fiber is along the extending direction of the frame, the flexibility can be improved, and even if the fishing line is caught, it is difficult to break. .

According to the present invention, Hakare weight reduction, the fishing line guide excellent in bending properties can be obtained.

Hereinafter, embodiments of a fishing line guide and a method for manufacturing the same according to the present invention will be described with reference to the drawings.
First, with reference to FIG.1 and FIG.2, 1st Embodiment of the fishing line guide which concerns on this invention is described. In these drawings, FIG. 1 is a front view of a fishing line guide, and FIG. 2 is a perspective view for explaining the state of reinforcing fibers in the fishing line guide shown in FIG. The arrow D direction in FIG. 2 coincides with the axial length direction of the fishing rod when the fishing line guide is attached to the fishing rod, and the fixing portion is attached to the fishing rod with the base rod side (see FIG. 1). FIG. 2 is a view as seen from the direction of arrow D). Hereinafter, the front side (front side) means the tip side, and the rear side (rear side) means the base end side (margin side). Further, the left-right direction is the left-right direction with respect to the axis X when the frame is viewed from the arrow D direction.

The fishing line guide 1 includes a so-called fiber reinforced resin frame 3 in which a reinforced fiber is impregnated with a synthetic resin. The frame 3 includes a holding portion 5 that holds a guide ring 20 through which a fishing line is inserted, and a fixing portion 6 for attaching a fishing rod that is fixed to the outer surface of the fishing rod. In the present embodiment, the holding portion 5 is provided. The connecting portion (support leg portion) 7 is provided between the fixed portion 6 and the fixed portion 6. That is, the fixing portion 6 is integrally formed by bending the end portion of the connecting portion 7 toward the base end side. As shown in FIG. 2, the connecting portion 7 is raised obliquely upward from the fixed portion 6 so that the fishing line is not easily caught.
By forming the connecting portion 7 between the holding portion 5 and the fixing portion 6, the fishing line inserted through the guide ring 20 ensures a certain gap with the outer surface of the fishing rod.

  The holding portion 5 is formed in a plate shape whose width in the left-right direction is larger than the thickness in the front-rear direction (arrow D direction in FIG. 2), and an opening for fitting the guide ring 20 in the center region thereof. 5A is formed. As will be described later, the opening 5A can be integrally formed when the frame 3 is molded by a mold. In addition, the connecting portion 7 is formed with a through hole 7A so as to be symmetrical at a position including the center axis X, so that the weight of the frame portion can be reduced.

  The frame 3 is formed of a fiber reinforced resin in which reinforcing fibers in a direction oriented in the extending direction of the frame are disposed. Reinforcing fiber includes a surface constituting the frame in the extending direction (the extending direction here is the direction in which the part of the frame formed with directionality is arranged) It is only necessary to include the one oriented in the direction extending in the vertical direction, whereby the flexibility can be improved. The parts constituting the frame 3 of the fishing line guide of the present embodiment are the direction in which the fixing portion 6 is inclined in the front-rear direction, the connecting portion 7 is inclined upward with respect to the axis X, and the direction in which the holding portion 6 circulates annularly. Each is extended with directionality. In addition, the reinforcing fiber in the present embodiment is configured by a plurality of reinforcing fibers being bundled (fiber bundle 10), and is disposed in the synthetic resin forming the frame 3 so as to be reinforced like an aggregate. I am doing. That is, the frame 3 of the present embodiment is formed of a fiber reinforced resin in which the above-described fiber bundle (bundle of reinforcing fibers) 10 is arranged so as to be continuous along the extending direction of the parts constituting the frame. . Therefore, the fiber bundle 10 is arranged so as not to protrude outside the frame 3.

  Specifically, the fiber bundle 10 of the above-mentioned continuous reinforcing fibers is connected to the one end side (the through hole 7A) of the connecting portion 7 from the fixing portion 6a on one end side (left side) with the axis X as a boundary. The left side of the connecting part 7 is folded so as to circulate around the opening 5A, passes through the other end side (right side of the through hole 7A) 7b of the connecting part 7, and the like. It continues so as to reach the end side (right side) fixing portion 6b. That is, as shown in FIG. 2, the fiber bundle 10 is continuously arranged along the frame shape, and the frame 3 is in a state in which the surrounding area is reinforced by the continuous fiber bundle 10. Yes.

Here, the configuration of the fiber bundle 10 will be described with reference to FIG.
FIG. 3 shows a cross-sectional structure of a part of the predetermined portion of the frame 3 (right connecting portion). As shown in this figure, the aggregate that becomes the fiber bundle 10 is arranged on the center side of the synthetic resin material, and the synthetic resin layer 15 is formed around the fiber bundle 10. Carbon fiber, glass fiber, aramid fiber, or the like is used as the reinforcing fiber constituting the fiber bundle 10, and the fiber bundle 10 has a core fiber 10 </ b> A arranged in the longitudinal direction and a periphery that goes around the core fiber 10 </ b> A. It is comprised with the fiber 10B.

  The core fiber 10A can be configured by bundling a large number of reinforcing fibers, and the peripheral fibers 10B can be arranged in a state of being knitted around the longitudinal direction of the core fiber 10A. In this case, the peripheral fiber 10B is configured by one fiber, but may be disposed around the core fiber 10A in a state where a predetermined number of fibers are bundled. Then, in a state where the reinforcing fibers are bundled as described above, this is covered with the synthetic resin layer 15 and is reinforced as an aggregate of the frame 3 of the fiber reinforced resin. When the fibers are knitted in this way, the synthetic resin enters the knitted spaces and is strongly held, and a frame having high strength can be obtained.

  Note that the fiber bundle 10 may be a frame reinforced with one fiber bundle or a plurality of fiber bundles, and not only in the center side of the frame 3 but also in a cross-sectional view. It may be in a state of being disposed throughout. Further, in the configuration shown in the figure, the fibers of the peripheral fibers 10B outside the respective fibers constituting the core fiber 10A have a large diameter, but both may be configured with the same diameter. The 10A fiber may be thick. Further, the fiber bundle may be one in which a plurality of reinforcing fibers are aligned in the longitudinal direction, one in which a plurality of reinforcing fibers are meandered so as to be entangled with each other, or one twisted together. The fiber bundle may be formed so that a space is formed between the fibers (the space is filled with the synthetic resin constituting the synthetic resin layer 15).

  In this way, by configuring the reinforcing fibers impregnated with the synthetic resin into a bundle shape, the handling becomes easy, and the frame can be easily formed as described later. Moreover, by making the multiple reinforcing fibers meander and entangle with each other, it is possible to improve the flexibility and improve the specific strength.

  The guide ring 20 is formed in a ring shape, and is formed of a member having a small sliding resistance at the fishing line guide surface 20a, which is the inner peripheral surface thereof, such as titanium, aluminum, SUS, ceramics, or the like. The guide ring 20 is fitted and fixed to the opening 5A formed in the holding portion 5 after the frame 3 is integrally formed using the fiber bundle as an aggregate.

Next, a method for forming the frame 3 having the above configuration will be described with reference to FIGS.
The frame 3 as shown in FIGS. 1 and 2 can be formed by a mold 50 shown in FIGS. 4 and 5. The mold 50 according to the present embodiment includes an upper mold 51 and a lower mold 52 that are divided vertically. FIG. 4 is a schematic view of the lower mold 52 opened from the upper mold 51 and viewed from above. The figure is shown. In this case, the lower mold 52 is formed with a mountain portion 52a having a substantially triangular shape in cross section where the one end surface is a gentle inclined surface 52b, 52c and the other end surface is a steeper inclined surface 52d. The fixed portion 6 of the frame 3 is formed on the 52d side, and the connecting portion 7 and the holding portion 5 of the frame 3 are formed on the gentle slopes 52b and 52c side. Note that the above-described mold 50 is merely an example, and the mold splitting direction can be set to an arbitrary form such as a horizontal direction or an inclined direction.

  A cavity (groove) 52C is formed along the entire shape of the frame 3 on the surface of the lower mold 52 (the surface of the peak portion 52a), and a through-hole formed in the connecting portion 7 is formed in the cavity 52C. According to the position of 7A, the through-hole convex part 52e and the opening convex part 52f are formed according to the position of the guide ring fixing opening 5A formed in the holding part 5.

  With respect to the cavity 52C of the lower mold 52, the fiber bundle 10 configured as shown in FIG. 3 is bent so as to follow the outer shape of the frame 3 as shown by a two-dot chain line in FIG. That is, the end side of the fiber bundle 10 is overlapped, and a loop corresponding to the connecting portion 7 and the holding portion 5 is formed in the middle portion and accommodated in the cavity 52C. At this time, it is preferable that the fiber bundle 10 is impregnated with a synthetic resin in advance and has shape retention when bent in a state before molding. As a result, it is possible to easily perform a bending operation and a mold housing operation for matching the fiber bundle 10 with the frame 3.

  In this state, the upper mold 51 is closed with respect to the lower mold 52, and the cavity is filled with a thermosetting resin (for example, epoxy resin) or a thermoplastic resin (for example, nylon) as a matrix resin. The resin can be cured to obtain the frame 3 made of fiber reinforced resin. In this case, the filled matrix resin constitutes the synthetic resin layer 15 shown in FIG. 3, but this matrix resin is also invaded between the fibers of the fiber bundle 10 described above. . Note that the fiber bundle 10 may be held in the mold so that the fiber bundle 10 does not move in the cavity during mold molding, and the upper mold 51 not only closes the cavity but also the lower mold 52. A pressing piece (not shown) may be provided so as to enter the cavity and press the fiber bundle 10 into the lower mold cavity.

  In addition, after taking out a molded object (frame) from an above-mentioned metal mold | die, resin molding (double molding) may be performed again by another metal mold | die, and you may make it a synthetic resin surround | circulate reliably. By doing in this way, it becomes possible to improve intensity | strength and an external appearance. Further, the frame 3 obtained from the mold is subjected to detailed processing as necessary. For example, the detailed processing may be performed by forming the shape of the fixed portion 6 of the fishing rod into a curved shape so that it can be easily placed on the fishing rod, or by polishing the end of the fixed portion so that it can be easily wound and fastened. Applicable.

  Next, the surface treatment of the frame 3 is performed. For example, by performing barrel processing, surface burrs are removed, and finish polishing is performed to such an extent that surface gloss is obtained. Regarding the degree of this polishing, it is possible to arbitrarily adjust the polishing agent, the polishing time, etc. according to the size, shape, material characteristics, etc. of the fishing line guide 1. By performing such barrel processing, the frame 3 can be polished without cutting the reinforcing fiber, the strength can be stabilized, and a fishing line guide having an excellent appearance can be obtained.

  In addition, when performing such a grinding | polishing process, it is preferable to grind | polish so that a part of reinforcing fiber may be exposed to the surface of the flame | frame 3, and a matrix resin may remain partially. By doing so, it becomes possible to further improve the gloss of the polished surface.

  Next, a film is formed on all or a part of the frame 3 as necessary. For example, it is possible to perform coating to improve the appearance and protect the frame body, or to deposit metal or ceramics.

  Then, the guide ring 20 is attached to the opening 5A of the holding portion 5 of the frame formed as described above. As a method for attaching the guide ring 20, any fixing method such as press-fitting, adhesion, curling, or the like can be employed.

  According to the fishing line guide 1 formed by the manufacturing method as described above, the weight is lighter than that made of metal, and further, the structure is excellent in specific strength, specific rigidity, and flexibility. This makes it possible to stably guide the fishing line. For this reason, even if a large number of such fishing line guides are mounted, the entire fishing rod is not increased in weight, and the performance of the fishing rod is improved. In particular, a portion such as a tip rod can be further reduced in weight, so that it is easy to sense delicate hits, and the performance of the fishing rod can be further improved.

  In particular, in the region of the holding portion 5 and the region of the connecting portion 7, by having the reinforcing fiber bundle 10 oriented in the extending direction as described above, the flexibility can be improved, so when the fishing line is caught, etc. Even if a large load is applied, breakage or the like hardly occurs. Further, in the region where the fixed portion 6 transitions to the connecting portion 7, the bending angle is large, and thus a large bending stress acts, but the state is effectively reinforced by the reinforcing fibers having such directionality. Therefore, it is possible to make it difficult to cause damage or the like.

  Furthermore, according to the manufacturing method as described above, it is possible to easily form a fishing line guide in which the reinforcing fibers are oriented in the extending direction of the frame.

  In the above-described configuration, the reinforcing fibers directed in the extending direction of the frame may not be a fiber bundle, but may be configured such that continuous reinforcing fibers along the frame are arranged with a space therebetween. good. Furthermore, the reinforcing fiber may be provided without interruption along the entire frame, but a continuous fiber along the extending direction is provided for each holding part, fixing part, connecting part, etc. of the part constituting the frame. May be.

  FIGS. 6 to 8 are views showing a second embodiment of the present invention, FIG. 6 is a front view of a fishing line guide, and FIG. 7 is a diagram illustrating the state of reinforcing fibers in the fishing line guide shown in FIG. FIG. 8 is a perspective view and FIG. 8 is a view for explaining a method of forming a frame constituting the fishing line guide shown in FIG. In the embodiment described below, the same components as those in the above-described embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the present embodiment, for the holding portion 5 in which the opening 5A for fitting the guide ring 20 is formed, in addition to the annular shape of the frame, a fiber bundle that makes one round of the annular holding portion 5a (second) Fiber bundle) 30 is disposed.

  The second fiber bundle 30 may have the same configuration as the fiber bundle 10, and may be formed in a C shape having a cutout portion 30 a as shown in FIGS. 7 and 8, for example. Or you may form in O shape, without forming a notch part. About the 2nd fiber bundle 30 comprised in this way, it may set first with respect to the cavity of the lower mold | type 52, and the 1st fiber bundle 10 may be set after that, or a fiber bundle may be set first. 10 may be set, and then the second fiber bundle 30 may be set.

  Or you may form not only attaching to the formation part of the holding | maintenance part of the 1st fiber bundle 10 but encircling this so that the cyclic | annular holding | maintenance part 5a may make one round. In addition, about the part which forms the cyclic | annular holding | maintenance part 5a, the continuous fiber should just provide at least half circumference rather than 1 round.

  According to such a configuration, it is possible to obtain a fishing line guide having excellent strength and strength made of a fiber reinforced resin having reinforcing fibers continuous along the frame, as well as the same effects as the above-described embodiment. In particular, it is possible to effectively reinforce the annular holding portion 5a on which the guide ring 20 on which the fishing line slides is mounted and the fishing line is easily caught.

FIG. 9 is a view showing a modification of the arrangement state of the reinforcing fibers shown in FIG.
In this modification, in forming the annular holding portion 5a, the second fiber bundle 30 is not provided separately, but the fiber bundle 10 of the first embodiment described above is made long, The structure which made 1 round in the part of the holding | maintenance part 5a is shown. That is, the fiber bundle 10 passes from the fixing portion 6a on one end side to the one end side (the left side with the through-hole 7A interposed) 7a of the connecting portion 7 and winds the annular holding portion 5a around the opening 5A once. It is folded so as to circulate, and passes through the other end side (right side across the through hole 7A) 7b of the connecting portion 7 to reach the fixing portion 6b on the other end side.

  Even if comprised in this way, it becomes possible to obtain the same effect as 2nd Embodiment mentioned above. Note that, in the above-described second embodiment and its modifications, the annular holding portion 5a may be further strengthened. For example, a fiber bundle similar to the second fiber bundle 30 may be further disposed, or the fiber bundle 10 may be wound two or more times.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to an above-described structure, It can change variously.

  In the present invention, as long as the frame portion constituting the fishing line guide 1 is such that the reinforcing fiber constituting the fiber reinforced resin is oriented in the extending direction of the frame. For this reason, about such a reinforced fiber, it does not need to be comprised in bundle shape. Further, the type of reinforcing fiber oriented in the extending direction of the frame, the modulus of elasticity, the resin impregnation amount, the diameter and the like, the arrangement state, and the like are not limited to the embodiment and can be variously modified.
